Spinner was missing from this machine ( the correct one). I ordered a repro "blank" from Pinball Resource, and Wotto was kind enough to draw the images from scratch (from photos). Cheers Mate 
I printed them on my inkjet on to adhesive paper, then applied them to the spinner. finally, I cut a piece of mylar and covered both sides of the spinner.
Nino, where do you source the adhesive paper (Officeworks?), and any particular type of adhesive paper to use? As Wotto has very kindly produced the artwork for the Surf Champ spinner I will soon be completing, and as I have never printed to adhesive paper before, I want to ensure I finish this right. I have an inkjet printer at home (HP), but have access to a laser printer at work (more tempted to use this one). Then of course to be covered with mylar.
I simply use White Inkjet Labels - Avery J8167. It is one big label - 25 sheets per pack. I only have an inkjet printer. I simply print the label and stick it (self adhesive) on the blank spinner. I then cover both sides with mylar. Works a treat - BUT - I would like to try other methods. Maybe waterslide decals etc ?
I don't think there is a "right way" to do it - I've just done it this way for years.
